Currently polling second in Australia's federal election (first in the Gold Coast), this feral may one day be your Bogan King.
Last year they opened with Zelda.
This year... I'm betting it'll be Retro's game.
Question is whether they'll open with the Wii U or 3DS. As the former is newer and a bigger deal, I'd normally think they'd go with that, but I also think they'll want to end on a positive note as well as a segue into hands-on stuff for the press. So I think they'll open with maybe a very short teaser for the Wii U, then move into the 3DS, otherwise open with some big 3DS reveal.
Then after the 3DS stuff is out of the way, they'll shift into Wii U mode.
